Security
Therefore, use the CSPMCR and port control registers to configure which control signal
is available on the external pin. All control signals, except for FB_TA, are assigned to the
ALT5 function in the port control module. Since, unlike the other control signals, FB_TA
is an input signal, it is assigned to the ALT6 function.
3.5.8.3 FlexBus CSCR0 reset value
On this device the CSCR0 resets to 0x003F_FC00. Configure this register as needed
before performing any FlexBus access.
3.5.8.4 FlexBus Security
When security is enabled on the device, FlexBus accesses may be restricted by
configuring the FBSEL field in the SIM's SOPT2 register. See System Integration
Module (SIM) for details.
3.5.8.5 FlexBus line transfers
Line transfers are not possible from the ARM Cortex-M4 core. Ignore any references to
line transfers in the FlexBus chapter.
3.6 Security
3.6.1 CRC Configuration
This section summarizes how the module has been configured in the chip. For a
comprehensive description of the module itself, see the module’s dedicated chapter.
